A must for deep sky fans. This eyepiece has the largest true field
possible for 2" eyepiece holders -3 times the field area of any
1 1/4" eyepiece. The focal plane is placed at the end of the barrel
to minimize vignetting. Performance with Schmidt-Cassegrains is
remarkable since it avoids the image degradation and severe vignetting
which occurs when using telecompressors. Long eye-relief and unique
adjustable eye guard for eyeglass wearers.

50 degree FOV, 20mm eye relief. Immaculate condition with both end
caps, box and original packaging.
